Abstract:: [Objective] The temporal and spatial variation characteristics of soil moisture and its response to rainfall under different cover types were analyzed, and the remodeling process of cover types on soil hydrology was discussed, which provided scientific basis for optimizing plant cover types and improving vegetation carrying capacity of soil moisture in Mu Us sandy land. [Methods] Grassland, salix land and bare land in Mu Us sandy land in Yulin City of Shaanxi Province were taken as research objects. The soil water dynamics in 0—150 cm layer and its response to precipitation were analyzed by combining annual in-situ observation and classical statistical analysis. [Results](1)At the annual scale, affected by the difference of vegetation root distribution and water consumption, the soil moisture of typical cover types could be divided into stable period(December to February of the following year), accumulation period(March to May), consumption period(June to August)and recovery period(September to November). Soil profile moisture showed obvious spatial differentiation, it was higher at 20 cm in grassland, it was higher at 50 cm and 150 cm in salix community. Plants in grassland mainly used soil water in 0—50 cm, salix mainly used 50—100 cm soil water.(2)The response of soil moisture to precipitation in shallow layer(0—50 cm)was slower than that in bare land, while that in deep layer(50—150 cm)was faster than that in bare land.(3)The depth of precipitation recharge was significantly positively correlated with precipitation, while the response lag time was significantly positively correlated with precipitation duration(p<0.05). [Conclusion] Vegetation type, precipitation duration, precipitation intensity and freeze-thaw process affect the redistribution of water in soil profile and dominate the succession of vegetation type under the change of precipitation pattern.
